In recent years, the food industry has developed rapidly and the demand for food packaging is large, which also means that environmental protection packaging is of great significance. And with the increasing voice of environmental protection and energy saving in the world, the market demand for food packaging bags is also increasing.
As we all know, environmental protection is a topic of common concern in today’s society. A large number of packaging wastes have caused tremendous pressure on the environment, among which packaging wastes account for a large proportion of food consumed every day. In addition, packaging wastes are mainly solid wastes, which are difficult to deal with. The main treatment methods of plastics are burial, decomposition and incineration. Buried plastics take 200 to 400 years to break down in nature, which can interfere with crop growth, cause digestive system diseases and even death of animals. Metal and glass containers are not contaminated, but they are too heavy and require a lot of energy to melt. Therefore, in the design, selection, use and recycling of food packaging bags, we should fully consider the environmental hazards and try to avoid them.
In order to reduce the harm of packaging waste to the environment, the concept of green packaging was put forward as early as ten years ago in China. At present, there is no complete definition of green packaging. Generally speaking, green packaging can be recycled, recycled or degraded, and it will not pollute the human body and the environment throughout the life cycle of the product. The most important significance of green packaging is to protect the environment, while it has the significance of resource regeneration. Food paper bags are environmentally friendly.
